The Constructive Carbon methodology was created to quantify the measurable environmental benefit of diverting construction and demolition (C&D) materials from landfill. Our goal is to transform recycling activity into verifiable carbon credits that support sustainability goals for municipalities, corporations, and developers while rewarding facilities for the recycling work they already perform.
This methodology applies to C&D recycling facilities, transfer stations, municipal diversion programs, and large-scale construction projects. It accounts for avoided emissions associated with diverting materials from landfill and channeling them into recycling, reuse, or recovery pathways.
To ensure accurate and trustworthy results, the methodology relies on documented and auditable data from participating facilities. Key inputs include total incoming tonnage, outbound recycled tonnage, material composition, diversion rates, facility processing data, and regional waste practices related to landfill emissions. All data must be collected in accordance with standardized reporting requirements.
Each participating facility undergoes independent third-party verification to confirm the accuracy of reported diversion data. This process includes review of scale records, material logs, facility procedures, site conditions, and documentation practices. Verified diversion results form the foundation for the issuance of carbon credits, ensuring transparency and integrity.
Once diversion tonnage has been verified, carbon credits are issued based on the calculated avoided emissions associated with keeping those materials out of landfill. Credits are generated on a periodic basis and entered into the Constructive Carbon Exchange, where they can be purchased, traded, or retired by buyers seeking to meet sustainability goals or offset the non-recyclable portion of their projects.
Credits purchased for environmental claims or compliance purposes are permanently retired on the Constructive Carbon Exchange. Retirement ensures that credits cannot be reused or resold, and each retired credit represents a documented and irreversible environmental benefit linked to verified C&D diversion activity.
Constructive Carbon uses a proprietary calculation framework to convert diversion data into carbon credits. This model incorporates material-specific factors, regional considerations, lifecycle impacts, avoided landfill emissions, and verification adjustments. While the general structure of the methodology is publicly available, the exact formulas, calculations, emission factors, multipliers, and modeling algorithms remain confidential to protect the integrity and security of the credit system.
